JavaScript/jQuery LoadPanel Options
See Also
closeOnOutsideClick
Use the hideOnOutsideClick property instead.
Event (jQuery or EventObject)
The event that caused UI component closing. It is a EventObject or a jQuery.Event when you use jQuery.
container
This property accepts one of the following values:
A CSS selector, or a jQuery selector if you use jQuery
jQuery
index.js$(function(){ $("#loadPanelContainer").dxLoadPanel({ // ... container: '#containerElement' }); });
Angular
app.component.html<dx-load-panel ... container="#containerElement" > </dx-load-panel>
Vue
App.vue<template> <DxLoadPanel ... container="#containerElement" > </DxLoadPanel> </template> <script> import { DxLoadPanel } from 'devextreme-vue/load-panel'; export default { components: { DxLoadPanel } }; </script>
React
App.jsimport LoadPanel from 'devextreme-react/load-panel'; // ... function App() { return ( <LoadPanel ... container="#containerElement" > </LoadPanel> ); }
A jQuery wrapper
jQuery
index.js$(function(){ $("#loadPanelContainer").dxLoadPanel({ // ... container: $('#containerElement') }); });
A DOM element
jQuery
index.js$(function(){ $("#loadPanelContainer").dxLoadPanel({ // ... container: document.getElementById('#containerElement') }); });
Angular
app.component.htmlapp.component.ts<dx-load-panel ... [container]="containerElement" > </dx-load-panel>
// ... export class AppComponent { containerElement: Element; constructor() { this.containerElement = document.getElementById('#containerElement') as Element; } }
Vue
App.vue<template> <DxLoadPanel ... :container="containerElement" > </DxLoadPanel> </template> <script> import { DxLoadPanel } from 'devextreme-vue/load-panel'; export default { components: { DxLoadPanel }, data() { return { containerElement: null } }, mounted() { this.containerElement = document.getElementById('containerElement'); } }; </script>
React
App.jsimport React, { useEffect, useState } from 'react'; import LoadPanel from 'devextreme-react/load-panel'; // ... function App() { const [containerElement, setContainerElement] = useState(null); useEffect(() => { setContainerElement(document.getElementById('containerElement')); }, []); return ( <LoadPanel ... container={containerElement} > </LoadPanel> ); }
The UI component defines the default container on its initialization. This default container can be one of the following (if the element is absent, the component selects the next one):
.dx-viewport
body
If you set this property to a specific element, the shading applies to this element. The LoadPanel calculates its size relative to the element.
copyRootClassesToWrapper
This property allows you to use CSS for wrapper element configuration. You can customize the shade, resize, and drag zones.
The following markup illustrates relations between wrapper and root elements when you set copyRootClassesToWrapper to true:
<body> <!-- The following element is the root element on which the component is initialized. --> <!-- Specify classes to be copied to the wrapper element here. --> <div id="loadPanel" class="custom-class" ... ></div> <!-- The following element is the wrapper element. --> <!-- Custom classes are automatically copied from the root element. --> <div class="dx-overlay-wrapper dx-loadpanel-wrapper custom-class" ... > <!-- The following element contains component content. --> <div class="dx-overlay-content" ... > <!-- ... --> </div> </div> </body>
deferRendering
Specifies whether to render the UI component's content when it is displayed. If false, the content is rendered immediately.
elementAttr
Use the wrapperAttr property instead.
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#loadPanelContainer").dxLoadPanel({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-load-panel ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-load-panel>
import { DxLoadPanelModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxLoadPanelModule ], // ... })
Vue
<template> <DxLoadPanel ... :element-attr="loadPanelAttributes"> </DxLoadPanel> </template> <script> import DxLoadPanel from 'devextreme-vue/load-panel'; export default { components: { DxLoadPanel }, data() { return { loadPanelAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import LoadPanel from 'devextreme-react/load-panel'; class App extends React.Component { loadPanelAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <LoadPanel ... elementAttr={this.loadPanelAttributes}> </LoadPanel> ); } } export default App;
height
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"20vh"
,"80%"
,"inherit"
.Function (deprecated since v21.2)
Refer to the W0017 warning description for information on how you can migrate to viewport units.
The LoadPanel calculates its height relative to one of the elements in the following priority: container => position.of => window.
hideOnOutsideClick
Event (jQuery or EventObject)
The event that caused UI component hiding. It is a EventObject or a jQuery.Event when you use jQuery.
The function passed to this property enables you to specify a custom condition for UI component hiding. For instance, you can prevent hiding until a user clicks a certain element.
jQuery
$(function () { $("#loadPanelContainer").dxLoadPanel({ // ... hideOnOutsideClick: function(e) { return e.target === $("#someElement").get()[0]; } }); });
Angular
import { DxLoadPanelModule } from "devextreme-angular"; // ... export class AppComponent { // ... hideOnOutsideClick(e) { return e.target === document.getElementById("someElement"); } } @NgModule({ imports: [ // ... DxLoadPanelModule ], // ... })
<dx-load-panel ... [hideOnOutsideClick]="hideOnOutsideClick"> </dx-load-panel>
Vue
<template> <DxLoadPanel .... :hide-on-outside-click="hideOnOutsideClick"> </DxLoadPanel> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxLoadPanel from 'devextreme-vue/load-panel'; export default { components: { DxLoadPanel }, methods: { hideOnOutsideClick (e) { return e.target === document.getElementById("someElement"); } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import LoadPanel from 'devextreme-react/load-panel'; const hideOnOutsideClick = (e) => { return e.target === document.getElementById("someElement"); }; export default function App() { return ( <LoadPanel ... hideOnOutsideClick={hideOnOutsideClick}> </LoadPanel> ); }

- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
- Paint server address
showIndicator
If this property is set to true, a message is displayed and a load indicator turns in a circle while the view's content is loaded. Set this property to false to display only the text message. This can help avoid problems with animation used for the load indicator when running on a slow device.
width
This property accepts a value of one of the following types:
Number
The width in pixels.String
A CSS-accepted measurement of width. For example,"55px"
,"20vw"

The LoadPanel calculates its width relative to one of the elements in the following priority: container => position.of => window.
wrapperAttr
Specifies the global attributes for the UI component's wrapper element.
jQuery
$(function(){ $("#loadPanelContainer").dxLoadPanel({ // ... wrapperAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-load-panel ... [wrapperAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-load-panel>
import { Component } from '@angular/core'; // ... @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxLoadPanelModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxLoadPanelModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxLoadPanel ... :wrapper-attr="loadPanelAttributes"> </DxLoadPanel> </template> <script> import DxLoadPanel from 'devextreme-vue/load-panel'; export default { components: { DxLoadPanel }, data() { return { loadPanelAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React, { useMemo } from 'react'; import LoadPanel from 'devextreme-react/load-panel'; function App() { const loadPanelAttributes = useMemo(() => { return { id: 'elementId', class: 'class-name' } }, []); return ( <LoadPanel ... wrapperAttr={loadPanelAttributes}> </LoadPanel> ); } export default App;
The code above specifies the id
and class
attributes for the wrapper element and produces markup similar to this:
<body> <!-- The following is the wrapper element. --> <!-- It is nested inside an element defined by the `container` property (`<body>` by default). --> <div id="elementId" class="dx-overlay-wrapper dx-loadpanel-wrapper class-name" ... > <!-- The following element contains component content. --> <div class="dx-overlay-content" ... > <!-- ... --> </div> </div> </body>
